To m7/ 11.71.0771/ it ptn/y concern.-

Be'it known that I, CHARLES CHURILLA, a citizen ofthe United States,residing at Allegheny, in the county ofl Allegheny and State ofPennsylvania, have invented a new and useful Improvement in Apparatusfor Lifting Street-Railway Cars, of which improvement the following is aspecification.

This invention relates to an improved'apparatus for liftingstreet-railway cars when derailed and placing the same upon the track;and it consists in the certain details of construction and combinationof'parts, as will be fully ldescribed hereinafter.

In the accompanying drawings, Figure 1 is a side elevation of myimproved apparatus adapted to be suspended beneath the floor of theplatform of a street-railway car, thesame being constructed and arrangedin accordance with my invention. plan view of a portion of arailway-car, showing my improved apparatus drawn upward to bring thesame some distance above the streetlevel, one of the saiddevices beingarranged at either end of the car. Fig. 3 is a detailed sectionalelevation taken through the drum. Fig. 4 is a sectional elevationshowing the worm and wheel used for bringing the arms Fig. 5 is aperspective view of a To put my invention into practice, I form fromcast metal aframe 2, of asuitable size and form and construction, andattach the same beneath the frame of the car 1, the said frame beingarranged in a vertical position and the connection formed by means ofball-bearings 3 in a manner that said frame may be free to revolve abouta central shaft 4, arranged therein. This shaft 4 is tted with a worm 5,which meshes with a worm-wheel 6, mounted in a casing 7 and adapted tooperate a drum 8 when said shaft 4is revolved by means of a removablehand-wheel 16. Hinged by means of a shaft 17 to the frame 2 is aswinging frame 13, in which is mounted a shaft 12, a worm-wheel 19, inmesh with a worm 18, the said worm being provided with a means ofconnection with a wrench-bar 27, the said barbeing suitably supportedand formed with a universal joint 28, as will be seen by refer- Fig. 2is an inverted l ence to Fig. 2 of the drawings. Loosely connected tothe shaft 12 are two cross-arms 11, the upper ends of which areconnected by chains 9 to the drum 8 l above and the lower ends fittedwith rollers 26, provided with intermediate toothed wheels 25, adaptedto engage with a rack 30, formed on the tread of `a short section of arail 23, which is loosely connected to said arms by inwardly-projectingportions 24, formed integral with the cross-arms.- Mounted on the sameshaft 12 is a gear-wheel 20, which is in mesh with two others, 21,rigidly attached to the short shafts 22, carrying the rollers 26. Asemicircular spiral spring 29 is passed about a portion of the frame 13and the ends connected to the will tend to draw the lower extremities ofthe same apart, thereby taking up the slack of the chains 9.

To replace a street car upon the rails end of the car, the device islowered by placing the hand-wheel 16, unwinding the chain 14 from theshaft 15, permitting the rail 23 to rest upon the street and at theproper angle with the rails of the track. By operating the wrench-bar 27with the same handwheel 16 the car may be moved to the -right or leftalong the rail 23 by the action of the several gearwheels abovedescribed. The entire weight ofthe car is supported upon thesedevices'and the car-wheels lifted clear of the street by the operationof the drum 8, which when turned by means of the worm 5 will draw theupper ends of the arms 11 together and impart a similar movement to thelower ends ofthe same, as is obvious. When the apparatus is not in use,the lower portion 13 and its connected parts are drawn upward byoperating the shaft 15.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, isg

1. The herein-described apparatus for lifting cars, consisting of theframe 2, suitably' mounted beneath the car-floor, and at each endthereof, the shaft 4 and worm 5 and a means foroperating the same, thedrum 8 operated by said worm, the swinging frame 1.3

upper ends of the arms 11 in a manner that equipped with my improvement,one 4at each' IOO attached lto the frame 2, the cross-arms 11, connectedto said swinging frame, and to the drum 8. the gearing' 2O and 2loperated by a- Worm and wheel, the rollers 26 and'gear 25,

mounted at the lower extremities of said arms, and connected to saidgearing, and a rail 23 carried by the arms 11, the said rail beingprovided with a rack 30, all arranged and combined for service,substantially as and for the purpose described.

2. In an apparatus for the purpose described, the combination consistingof the pivoted frame 13, a central shaft mounted therein, a drumoperated by saidshaft` a hinged frame carrying cross-arms, means forattaeh- I5 ing said arms to said drum, rollers carried by the arms and ameans for bringing` the lower extremities of said arms together, as andfor tbe purpose described.

In testimony whereof I have hereunto signed 2O myname in the presence'of two subscribing Witnesses.
